PNEUMATIC WATER-ELEVATOR. Y

Specification of Letters Patent.

Patented Feb. 25,1919.

Application filed June 8, 1917. Serial No. 173,531.

To all whom it may concern.-

Be it known that I, FELIX DENIZET, a citizen of the United States ofAmerica, a resident of Perryville, in the county of Perry, State ofMissouri, have invented certain new and useful Improvements in PneumaticTater-Elevators, of which the following is a full, clear, and eXactdescription, reference being had to the accompanying drawings, forming apart of this specification. Y

My invention relates to an apparatus for raising water by air pressurefrom wells or other basins and conducting it to any point to which itmay be desired to make delivery. The invention has for its object theproduction of a simple apparatus of this kind which is automatic inoperation, and which is of such simplicity as to be not liable to becomeinoperative or impaired by long continued use.

Figure I is a vertical section, partly in elevation, of my waterelevator.

Fig. II is an enlarged side elevation of the mechanism for controllingthe vertical movement of the submerged tank of my water elevator.

Fig. III is an elevation of the parts shown in Fig. II viewed from apoint at a right angle to the point from which the parts in Fig. II areseen. Y Y

Fig. IV is an enlarged section on line IV-IV, Fig. III, through thecontrolling valve of the elevator.

In the accompanying drawings, 1 designates an upper horizontal anchorbeam or stay which serves to position a frame comprising vertical rods2. The rods 2 extendto the bottom of the well or basin B from whichwater is to be elevated and have fitted to them at their lower ends abottom stay bar 3 provided with a vertical guide 4.

5 designates a tank submerged in the water in the well or basin Badapted to partake of limited upward and downward movements to providefor the actuation of certain controlling elements, as will hereinafterappear. The tank 5 is in part directed during its vertical movement andheld from turning by a non-circular stem 6 at the bottom of the tankfitted to the guide 4. A horizontal stop bar 5' secured to the verticalrods 2, and further held from upward connecting said cross bar to thebottom stay bar 3, serves to limit the upward movement of thetank 5.

The tank 5 is provided with a water inlet 7, controlled by a valve 8which opens automatically when the pressure in the basin B is in excessof the pressure in the tank 5, but is held closed by pressure in thetank 5 when the pressure in the tank is in excess of that in the basin.

9 designates a vertical section of pipe fixed to the tank 5, said pipesection being disposed partly within and partly above said tank. Thepipe section is telescopically fitted to a vertical water discharge pipe10.

11 designates a U-shaped hanger depending from a horizontal supportingbar 11 secured to the rods 2. A shaft 12 is journaled in the legs of thehanger 11 and has fixed to it a pinion 13, in mesh with a rack 14:secured to the pipe section 9.

A 3-way valve C located at the lower end of the hanger 11 comprises ahousing 15 secured to said hanger and a ported plug 16 in said housing,which is fixed to the shaft 12 and is rotatable therewith. The 3-wayvalve C serves to control the delivery of air under pressure from aconducting pipe .17 to the interior of the tank 5, and the escape of airfrom said tank, as will hereinafter appear.

The air under pressure may be delivered from an air compressor or other"suitable source of supply through the conducting pipe 17 leading to thehousing of the 3-way valve 0, and when the plug of said valve is in theposition in which it is seen in Fig. IV, the air in the pipe 17 willpass to a pipe 18 leading to the interior of the water delivery ipe 10,said water delivery pipe preferably including a union 19 through whichthe pipe 18 enters the pipe 10. The pipe 18 extends downwardly in thewater delivery pipe 10 to the lower end of the latter, and preferablyleads to the exterior of said pipe within the tank 5 and then upwardlyin said tank to a point near the top of the tank, as seen in Fig. I, sothat the air passing through the pipe 18 may be discharged above thelevel of water in the tank 5. Y e

The housing of the 3-way valve C is provided with-a duct 15, which isopen to the atmosphere and which is adapted to be placed in registrationwith the pipe 18 when Y 20 designates a tri arm fixed to the shaft 1.2by which the 3-Way valve C is operated. This trip arm is preferably inthe form of a sector and is located at the end of said shaft opposite tothat at which the 3-way valve C is located. At one side of the trip arm:isa trip pin 21, which is movable in an arc of a circle and is adaptedto be shifted with the trip arm from one side of a vertical line drawnthrough the axis of the shaft 12 to the other side ofsaid vertical line.

;22 designates a vrockable controller pivoted intermediate of itsends at23 to the hanger 11, said controller comprising an upper arm providedwith a counterbalance weight 22 and a lower arm bifurcated to producedivergent legs 24 and 25, each of which -is adapted to be engaged by thetrip ;pin 2 1.on the trip arm .20.

-26 designates a detent device pivoted to the'hanger ,11 ;.at 23, saiddevice being provided with .a pairof spaced pendent arms 27 adapted toengage the triparm 20, when said armis .ineither of its extremepositions. Atthenpper endof thedetent device 26 are ;arms,28 providedwith abutments 29 and 30 between which the upper arm of the rockableeontroller 22is operable, and which are adapted to belengaged bysaid upper con- ,trollerarm when it is rocked to and fro on its point fpivotal support.

'Thehanger 11 is preferably formed with an elbow .1:1. locate d at itslower end, which extends transversely of and straddles the pipe section9. Thiselbow serves as a sup port for a ;roller 11 located opposite the"pinion 13, between which and said pinion ztlle pipe sectionQ isdirectedin its vertical .movements. 7

In the practical use of my automatic waterelevator theoperation is asfollows: When ,the tank .5 is supplied with water to be withdrawntherefrom through the discharge pipe 10, said tank is submerged, as seenin Fig. and the inlet valve 8 occupies a closed position. At this timethe plug 16 pf the valveC is in the position in which it s seen inIV,-so that there is communic ation between .theair pipes 17 and 18 andair under pressure :maytherefore be delivered t0 the-interiorof the tank5 to exert pressure against the .water in said tank and force it throughthe delivery pipe 10 to the point at which it is desired to deliver thewater. WVhile water is being discharged from the tank through thedischarge pipe, the valvelplug 16 ismaintained in the position in whichitgisseen in Fig. IV, due to the ,holding influence of the detent device.26, ,the arm 2 o which a t ga st he .trip ,arm 20 and is held theretoby the weighted :QQHtlTOllBP 22 lying in engagement with the abutment 30of the detent device 26. The weighted upper arm of the controller 22constitutes a counterbalance and in full lines Fig.

isshifted to the basin B against the tendency of the tank 5 to float inthe water in the basin B when the tank has become. Jartially emptied byremoval of water there rom through the discharge pipe 10, and all of theparts of my water elevator will retain the positions shown in Figs. I,III and IV, and in full lines Fig. II, until the tank has becomesufliciently emptied to commence to rise in the basin B, due to itsbuoyancy. Upon the tank having been emptied t0 the degree just referredto, it rises and carries with it the pipe section 9 and the rack 14thereon. As a consequence of the upward movement of the pipe section 9,the rack 1 1 operates to rotate the pinion 13 and the shaft 12 to whichthe latter is fixed, whereby the valve plug 16 is turned to closecommunication between the air conducting pipes 17 and 18 and establishcom munication between the pipe 18 and the vent duct 15 of the valvehousing 15, so that air may be vented from the tank 5 to the atmosphere.

During the rotation of the shaft 12 to change the position of the valveplug 16 of the valve C, the trip arm 20 rotates with said shaft towardthe right hand relative to the position in which it isseen in Fig. I,II, and the trip pin 21 carried by said arm strikes the leg 25 of thecontroller 22 while said trip arm is moving to the dotted line position,Fig, II, and in consequence of this movement the controller dotted lineposition, Fig. II, and shifts the detent device 26 to the dotted lineposition, So that the valve plug 16 may be completely shifted from theposition shown inFig. IV, and the tank-5 may rise to the limit of itsintended upward movement. In shifting to the dotted line position-shownin Fig. II, the controller 22 strikes the abutment 29 of the detentdevice 26 and causes the leg 2 7. 0fsaid detent device to engage thelefthand edge of the trip arm 20, thereby providing forthe temporarydectentionof said trip arm and the valve plug 16 in ,the positions towhich they have been adjusted.

It will be readily understood that when the parts are in the positionslast recited the tank 5 is in an elevated position, and inasmuch as thecompressed air pressure in the tank has been relieved there isopportunity for the pressure of the Water in the to open the inlet valve8, which therefore opens and water is admitted to the tank .to fill it.As the tank becomes filled it settles in the water in the basin untilgit reaches the limit of its downward movement, and there is resultantreadjustment .of the shaft 12, valve plug 16, trip arm .20 andpartsopera'ble by said trip arm to their original positions. As will beapparent, when the trip arm returns to its original position the stud 21strikes the leg 24 of the controller 22, and said controller is tiltedfrom thedotted line position, Fig. II, to the full line position, Fig.II, with the result of causing the detent device 26 to again engage thetrip arm 20 and hold it from movement until the tank 5 again movesupwardly by flotation. An important feature of my water elevator is theconnection of the air conducting pipe 18 to the water delivery pipe 10,and the support of the air pipes 17 and 18 and the air controlling valveC, so that these parts will remain stationary when the tank 5 and othermoving parts partake of movement. Such arrangement avoids the use offlexible pipes such as rubber tubing, which has heretofore been used inwater elevators of the type to which my invention belongs, and whichbecome unserviceable after a short time.
